Step-by-step explanation:
refer the above attachment
Use Pythagoras to get the height, the use it to find x:
26^2-11^2 =555
555^1/2(square root of 555)
=23.55843798 ~you need this number left as it is for a more accurate answer.
Then you do
42^2-23.55...^2(which we know is 555)
Then whatever that equals you square root that
Then you round up the answer to that to get the final answer.
I left the last part so you can do it and do some active learning, if you have more questions on this please feel free to ask, hope this helps
The value of x in the equation
is x=(7+3
)/2,
(7-3
)/2.
Given equation
.
We have to find the solution of the equation.
Equation is solved to find the value of variables. The number of values of the variable depends on the highest power of variables.
let (x-5)=u-------------------1
equation becomes 
solution of a quadratic formula
x=-b±
/2a
on comparing with general form a=1,b=3, c=9
u=-3±
=-3±
=-3±
=-3±
+3
,
=-3-3
put the values of
in equation 1
x-5=
x-5=-3+
x=-3+3
x=7+3
put the values of
in equation2
x-5=
x-5=-3-3
x=7-3
Hence the values of x are 7+3
, 7-3
.
